Shulou(Shulou.com)11/24 Report--

According to CTOnews.com news on April 3, Xiaomi officially announced today that its Ranging_SL technology has been approved by the 99th Plenary session of 3GPP CT and 3GPP SA, which means that Xiaomi has achieved omni-directional coverage and leadership in the three working groups of RAN, SA and CT of 3GPP, and will continue the relevant research of RAN WG2, SA WG1 and SA WG2 in the Ranging_SL project, and will continue to lead the research of Ranging_SL in the SA WG3 and CT WG1 working groups.

Xiaomi said: this not only reflects Xiaomi's important position in 5G technology, but also lays a solid foundation for Xiaomi's development in the 6G era. It is worth mentioning that in addition to the Ranging_SL project, Xiaomi continues to invest in many cutting-edge research in 3GPP, such as satellite, synaesthesia integration and so on.

CTOnews.com Science Popularization: 3GPP is a standardization organization for formulating global mobile communication technical specifications. There are three TSG (technical specification groups) of RAN (wireless access network), SA (service and system) and CT (core network and terminal), and multiple WG (working groups) are set up under each TSG.

The mobile communication standards that we are familiar with from 2G to 5G are formulated by 3GPP. At present, 3GPP is in the stage of transition from 5G-A (5.5G) to 6G, and the next few years will be the key period for the formulation of 6G international standards.

According to reports, the full name of the Ranging_SL technology led by Xiaomi is Ranging based services and sidelink positioning, which determines the distance and angle between terminal devices through the PC5 interface.

Figure 1:3GPP SA2 Ranging_SL standard document TS23.586 Xiaomi believes that Ranging_SL technology will become one of the important means to achieve high-precision positioning in the 5G era, which can be used in commercial, V2X (vehicle networking) and public safety cases in three scenarios: inside, partially and outside 5G network coverage.

Xiaomi, a museum guide with examples of the application of 2:Ranging_SL technology, said that the completion of Ranging_SL standards will further promote the landing of products equipped with Ranging_SL technology. In the near future, Ranging_SL technology will make the products of Xiaomi ecological chain more accurate and convenient in navigation, positioning, map and so on. Ranging_SL technology will also help lighting, security, entertainment, home appliances and other aspects of the whole house intelligent, so as to "moisten everything quietly." For example, when the user returns home, the light in the user's room will be turned on automatically; when the user turns on the Xiaomi TV, the Xiaomi TV can automatically set relevant parameters according to the user's position in the room. to help users achieve an immersive audio-visual experience without dead corners in the whole house.
